C# to VB.Net Syntax conversion

Can any one translate the following syntax to vb.net.

m_TextBox.Loaded += TextBoxLoaded
m_TextBox.Loaded -= TextBoxLoaded;
private void TextBoxLoaded(object sender, RoutedEventArgs e)
 {
   Init();
 }

..
containsTextProp.AddValueChanged(m_TextBox, (sender, args) => UpdateAdorner());
...
private void UpdateAdorner()
        {...}

Here it is:

AddHandler m_TextBox.Loaded, AddressOf TextBoxLoaded
RemoveHandler m_TextBox.Loaded, AddressOf TextBoxLoaded

Private Sub TextBoxLoaded(ByVal sender as Object, ByVal e as RoutedEventArgs)
    Init()
End Sub

Your call to AddValueChanged can't be directly translated, as VB.NET's lambda expression support is not as robust as C#'s. In particular, VB.NET lambdas must be an expression, so you must either return a value or call a Function. In your case, you would be calling a Sub, which isn't allowed in VB.NET. You should consider changing the signature of UpdateAdorner to be a standard event handler (like the TextBoxLoaded method) and pass AddressOf UpdateAdoerner to AddValueChanged.

Like this:

containsTextProp.AddValueChanged(m_TextBox, AddressOf UpdateAdorner);

...

Private Sub UpdateAdorner(ByVal sender as Object, ByVal e as EventArgs)
    ... 
End Sub

There are plenty of online converters, you shuold probably try that first next time and post here if it doesn't work or you have a problem.

AddHandler m_TextBox.Loaded, AddressOf TextBoxLoaded     ' per @Adam Robinson'
RemoveHandler m_TextBox.Loaded, AddressOf TextBoxLoaded  ' per @Adam Robinson'

Private Sub TextBoxLoaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
  Init()
End Sub

Private Sub UpdateAdorner()

End Sub

You can toss it in an app, build it, then open the app in .NET reflector. .NET Reflector can take the IL and "turn it into" C#/VB.NET, etc.
